SIM card related Projects » pySim

When using pySim-prog, the value of the Ki written on the card is shifted by on hex digit to the left and an extra 0xFF is written at the end. pySim-prog display the values as passed as parameters, but not the actual written values.

./pySim-prog.py -p 0 --iccid=8988211910000000987 --pin-adm=11111111 --mcc=214 --mnc=03 --imsi=214030123456789  -k 00ffeeddccbbaa998877665544332211@

I haven't found a way to read the Ki value using pySim-shell or pySim-read, so I used simso-isim-tool.sja2.py to verify the card content.

./sysmo-isim-tool.sja2.py -a 11111111 -k

Done!

The value recognized by the network is indeed the key as read by sysmo-isim-tool.sja2.py

Both tools are used in their most recent version, retrieved last week.
